I try to keep my comments civil on here, but that's horrible fucking advice. The best thing you can do is try and relax and calm down, taking more of a drug you're having a bad experience with is the opposite of what anyone should do ever.
There is wisdom in it. Some drugs have a kind of scuzzy zone somewhere between a mild dose and next level dose. If you're taking a drug that perforce requires you to "let go", it may help take enough that you lose agency to resist.
Actually I have experience with lsd, mushrooms and some other hallucinogens. I've gotten really high on them. I've talked about it in my comments here before. I still believe it's bad advice especially for inexperienced users.
